Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 2-((3-Cyano-6-(4-methoxyphenyl)-4-phenylpyridin-2-yl)thio)-N-(4-methyl-3-nitrophenyl)propanamide (CAS 332155-79-0), a certified reference material (molecular formula C29H24N4O4S, MW 524.59 g/mol) for analytical method development and quality control.
The molecular framework of 2-((3-Cyano-6-(4-methoxyphenyl)-4-phenylpyridin-2-yl)thio)-N-(4-methyl-3-nitrophenyl)propanamide (C29H24N4O4S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
